我想检查 Ubuntu 14.04 下 SSD 的状态，因此我使用以下命令：
smartctl -a /dev/sda | grep Media_Wearout_Indicator
sudo smartctl -a /dev/sda
输出结果如下：
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-57-generic] (local build)

我认为我必须更换固态硬盘或进行备份，对吗？
值230 Life_Curve_Status和231 SSD_Life_Left看起来很糟糕，我错了吗？
答案1
该231 SSD_Life_Left值为 100，失败阈值为 10。
与 相同230 Life_Curve_Status。值为 100。
实际上这些参数看起来很完美。
